' Devices for Se\ving-Mac-hines, of which the followin is a description, reference being had to tie accompanying drawing and to the letters and figures'of reference marked -thereon.

- My invention relates to an improvement in folding devices for attachment to sewing machinesand particularly to a device for use upon what is known as acollaret machine, for use in securin a band upon the neck of undershirtsand t e like.

The'collaret is preferably formed of a strip of material and is usually first folded in the center lengthwise, the folded edge being overscamed or formed with an ornamental edge seam; then the collaret or band is fed to a sewing machine through a foldmg guide which turns a bent on each raw edge of the strip and folds it in the center again and it is secured by a line -or lines of stitching which pass throu h the folded edges and a main body fa ric which is guided between the layers of the collaret strip.

The object of the present invention is to provide a special form of folding device for guiding this s0-called tipped collaret so as to prevent any friction or'strai'n upon the folded edge thereof 'or ornamental stitches on said edge, tilt is provided with such, while the band is passing through the folder.

The invention also includes features for exerting the proper tension upon the band in the appended claims.

'The invention is illustrated in the accom panying drawings in which-- f Figure 1 represents a; perspective view of a folding device constructed in'accordance with my invention, Fig. 2 is a perspective ,viewfrom the opposite side of Fig. 1; Fig.

3 is a face view looking in the direction of the arrow, Fig.1. Fig. -il 18- a section on line H of Fig. 2, and Figs. 5 and 6 are res ectively sections on lines 55 and 6-6 of 'ig. 2.

In these drawings, A represents the flat portion or base piece of the-folder, which is secured to the bed plate of the sewing machine in any suitable way, and upon which the body portion of the fabric to which the collaret is to be secured rests. This base piece is formed as shown, with folding and guiding recesses a, (1, adjacent the stitchforming mechanism of the sewin machine,

which recesses gradually taper own from the widened portions 'b'of the folder proper, and these tapering portions a, a, turn the edges of the collaret around the body fabric.

hold the edge or tipped portion of the collar-ct in said recess. The object of the 1ecessed rib or guide in the folder is to provideroom to take that portion of a collaret strip which, when the strip is laid out flat is at right angles to the body thereof. When the strip is in the folder it occupies a ver tical position, and the verseaming stitcln in the pas or tipped portion of the collaret occupies a horizontal' position and this space is provided in the walls of the folder for it.

As shown in' the drawings, thereare at: tached to the end of the folder 'roperB, farthest away from the stitc -formin mechanism,-two vertically arranged curve plates D, spaced apart so that room is left 1 between them for the passage of the tipped portion of thecollaret and one of them'is I providedwith a rib e, which atone end opens'into the recessed rib c. Bands of metal F, attached to the two plates D hold i the same properly spaced apart, and serve as walls parallel with the plates 1) to guide the strip or. band to; be sewed and flat springs G and H are provided to keep the tipped portion of the collaret in'its proper position in the space between the plates- D.

The flat portion of the folder, it will be noticed, has its upper surface on a line which if extended, would enter the recessed rib for the collaret tip, as shown in Fig. 5. This is desirable, as the support or platform for the body of the garment must be on a line with the collai'et and that portion of the fabric which is tipped as the latter must come to the very top.

As shown at f, an open groove is formed through the face of the attachment for threading the strip into the folder.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A folding device comprising a bod portion lli'fl'lil" along its length a channe foimlli" rib, tlie latter projecting from the back of the said bodyiortion and in a direction o )POSllJQ that o the folding portion of said (evice, said rib having a channel formed therein for receiving the rib or selvage of the work.

9. A folding device coinprisin a bodyportion having hem-turning devices at its opposite edges and between said devices, a channel for uidiii the body of the work, and said l)0( y-portion also havin between said devices a longitudinally exten ing channel-forinin rib for receiving the rib or selva e of t ie work.

3. folding device having a portion provided with hem-turning devices at its oppos site edges, and adjacent each of said devices with a passage for guiding the body-part of a piece of binding, and said portion being also provided remote from said turnin -devices with means for aiding the ri or selvage of said piece of inding, said means being arranged at the junction of said bodypart-guiding passages, and a plate for supporting another piece of work, said plate extending between the said hem-turnin devices, substantially parallel to the sai ribguiding means and with its supporting surace at the lower edge of said means, whereby the edge of one piece of the work may be led between the hemmed edges of the other piece of the work and close to said rib or selva 'e.

4. 7t folding device the body-portion of which has a cliannel-forining rib extending from end to end thereof for receivin and guiding the selva e of the work, an said ody-portion also iaving means on opposite sides of said rib for folding one portion of the work upon another and also for liemlniing the edges of both portions of the wor t.

5. A foldin device for sewing machines including gui in walls forming a guiding recess for the body of the bindin stri or band, said guiding walls bein s ape at their outer edges to provide folding recesses for folding the edges of the strip or band,

the outer wall between its edges having a recess therein to receive and guide a tip or rib projecting from the outer face of said strip or band intermediate its edges.

6. A folding device for sewing machines including guiding walls forming a guiding recess for the body of the binding strip or band, said guiding walls bein shaped at their outer edges to provide folc ing recesses for folding the edges of the strip orbaiid,the outer wall between its edges having a recess therein to receive and guide a tip or rib pro- 'eetin from the outer face of said strip or and intermediate its edges, and means for holding said tip or rib within the guiding recess.

7. A folding device for sewing machines, comprising guiding means for guiding and folding a strip or band to be sewed and means extending from the receiving to the delivering end of the folding device for receiving and guiding a tip or rib projecting from said strip or band, intermediate its edges, and a spring finger rigidly secured to the guiding means for the strip or band and operating to hold said tip or rib within its reeeivin and guiding means; substantially as descri ed.
